FIX: prevents user-tips to interfere with widget (#23066)

Prior to this fix the user tip was rendered with panels and interfering with widget code. I suspect it was causing the widget node  (revamped-hamburger-menu-wrapper) to not be removed, as a result clickOutside would be called two times, negating the effect of the click.

This fix is just rendering the tip in a different node, preventing the interference, it shouldn't impact behavior as the positioning is absolute.
